We have Weblogic12c. I configure the Java startup args to enable remote debugging.
jdb -attach <address>:<port>
works locally (and connects quickly)
jdb -attach <address>:<port>
from another machine hangs indefinitely.
telnet <address> <port>
connects, so it's not a basic connectivity issue.
Tunneling the port with ssh does work remotely, so it really looks like non-local connections are the issue.
Is there an ACL or something saying where connections will be accepted from?
Any other ideas what the problem could be?
